IMPROVEMENT IN STOVES.

Specification forming part of Letters Patent No. 157,950, dated December22, 1874; application led March 14, 1874.

To all whom it may concern:

Be it known that I, GEORGE W. WALKER, of Malden, in the county ofMiddlesex and State of Massachusetts, have invented an Im provement inStoves; and I do hereby declare that the following, taken in connectionwith the drawings which accompany and form part of this specification,is a description of my invention sufficient to enable those skilled inthe art to practice it.

This invention consists in arranging the supporting-slide ofthegrate-journal in an independent ianged cap -plate or pocket, detachablysecured to the outside of the stove or furnace, as hereinafterdescribed.

In my invention I support the journal end in a slide running in a pocketat the front part of the stove, this pocket being so made that its frontplate is detachable without taking down any other parts of the stove,and the removal of this plate enabling the slide to be applied orremoved, as may be desirable.

The invention consists primarily in supporting the grate-journal in theslide that runs in a pocket between the main casting and a eapplate,preferably made detachable, for application or removal of the slide.

The drawing represents the bottom part of an ordinary furnaceembodyingmy invention.

Figure 1 shows the same in plan. Fig. 2 is a front elevation. Fig. 3 isa section, enlarged, vof the slideplate and adjacent parts. Fig. 4 is arear view of the plate that carries the slide.

a denotes the eastin g that forms the ash-pit; 12, the ash-pit door 5 c,the center support for the circular grate d, the grate rotating andtipping upon this support. e denotes the grate journal, shaft, orgudgeon, which, extending from the front side of the grate, passesthrough the front plate f of the stove or furnace, for attachment of ahand-bar, by which the grate is shaken or tipped. In front of this platethere is formed a pocket, g, in which is placed and reoiprocates aslide, It, the shaft e being jourualed in this slide.A The pocket isformed between the main plate f and a flanged eapplate, i, and thiscap-plate I prefer to fasten to the front of the plate f by ears k andscrews l, or by other suitable means, the slide being made accessibleand attachable and detachable by removing the cap. Ihe slide thusinclosed I mount upon friction-rolls m m, journaled in suitablebearings, said rolls insuring free movement of'the slide withoutliability to clog or bin d. rlhe slide is shown as placed between thefront wall or plate i and guidesurfaoes n o, above and below the innerslot p, in which the journal reciproeates. The capplate t' may be castwith or as a part of the plate f, as shown in Fig. 5, in which case theguide n will be a lip or flan ge extending down to the journal, theguide o being then prefera bly formed as a lip or flange extending upfrom the plate q, beneath the slide, this plate being held by suitablebuttons orother fastenin gs, and preferably so that by removing theplate p, and bringing the slide to central position, it will fall fromthe pocket.

I am aware that a journal-supporting slide has moved in ways cast in andback of the door of the ash-pit, and to remove the grate it wasnecessary to first remove the door-frame and door from the furnacea longtedious job. By my invention I obviate this, as the journal-supportingslide moves in a way formed in an independent anged cap-plate, which maybe easily removed by withdrawing two screws and allowing the grate to beremoved or replaced, no other portion of the furnace being removed.

I claimj I. The combination, with the outer side of the stove, of theindependent flanged capplate t' and the detachable journal-supportingslide 7L, as and for the purpose described.

2. The combination, with the outer surface of the stove and theindependentanged capplate, of the detachable journal-supporting slide hand the rollers m m, substantially as shown and described.
